Obthnand the moment coefcent about the aerodynamic cente Obtan the moment coelficient about the erodynamic cnter 3.How do the lift and moment coefficients compare in configuration I,configuration II and the no defection case (=0) After solving this problem,you should be able to see that a slat generates less extra lift than a flap.In fact,the function of the slat is a different one.A slat re-directs air from the lower part of the airfoil to the upper one at the leading edge,preventing boundary layer separation at a high angle of attack.This allows the wing to be operated effectively at higher angles attacka group o tarily at high Alula feathers Figure 3:Alula feathers in a landing male mallard.
